Since FreeRepublic allows for posting HTML, it also goes ahead and strips out incorrect HTML, like those wonderful sarcasm tags that we like to use. Seriously, this is very important when replying to any topic that mentions Hitlery, Jesse Jackson, etc.
<xmp><sarcasm></xmp>
Boy is Hitlery purty!
<xmp></sarcasm></xmp>
If you do this properly, your post will look something like this...

Hitlery for President in 2004!!

This is an important part of posting, as it preserves the flow of the conversation, and makes it easier to allow others to joinin the discussion. FreeRepublic does include a great feature that allows you to see the original post, but including the reply in your post is a Good Thing®.
It's a lot easier to type < and > and you get < and > respectively.
Also, in posting Images, make sure you add the width="xxx" and height="xxx" parameters to prevent the threads from hanging up during load.
Thanks so much for this hint! (You'll notice I had to use it to post this reply -- always good pedagogy! Though I also had to lift your code for the <xmp></xmp>. Some things there's no clear-cut way around!)
